for one set only ... he had lost two sets before and very near to losing another one which Rosol choked a little bit
Oh I agree. Bad knee or not, Rosol played incredible, especially in that fifth set. Deserved to win. But if Nadal needs to justify that loss to himself then fair enough - after all Federer seems to never have the confidence knocked out of him - not bad for Nadal to learn some of that... I think he recognises that Rosol was good that day, but he also tells himself that "I wasn't by best" - easier to accept losing to the world no.100 that way!
